- 前記後端部接合機構が、前記後端部の上面側に配置されて幅方向に延在する押圧バーを有し、この押圧バーを前記後端部の上面に向かって移動させることにより前記後端部が押圧されて、前記後端部が前記外周面上の前記前端部に接合される構成にした請求項1〜3のいずれかに記載の未加硫の環状ゴム部材の製造装置。
- それぞれの前記移動部の前後方向の移動速度が同じ速度に設定さている請求項1〜4のいずれかに記載の未加硫の環状ゴム部材の製造装置。
- 未加硫の帯状ゴム部材を搬送コンベヤによって成形ドラムに向かって搬送し、前記帯状ゴム部材の前端部を前記成形ドラムの外周面上に配置して、前記成形ドラムを回転させることにより前記帯状ゴム部材の所定長さを前記成形ドラムの外周面上に巻き付け、前記外周面上の前記前端部と前記帯状ゴム部材の後端部とを、予め設定されている許容接合しろで接合する未加硫の環状ゴム部材の製造方法において、
前記後端部を、前記帯状ゴム部材の幅方向に並列された複数の保持部により保持して、それぞれの前記保持部をそれぞれの移動部により個別に前後方向に移動できる状態にして、前記後端部を前記前端部に接合する前に、前記帯状ゴム部材の幅方向での長さの分布データを用いて、制御部によりそれぞれの前記移動部の前後方向の移動量を制御して、それぞれの前記保持部によって保持されている前記後端部の被保持部分周辺の前後方向の伸長程度を調整することを特徴とする未加硫の環状ゴム部材の製造方法。
